` DISPENSING- NOZZLE Appneation mea 'April 15,

My invention consists of a .novel construction of a dispensing nozzlefor Veecting the conveying of compressed air or other fluid to a desiredpointy by means of a handle or body member, a fixed pipe therein, aslidable plunger mounted on said pipe and having a transverse flangeadaptedv to effect the actuation of the valvular elements, said plunger`being suitably packed and under tension withrespect to said fixed pipewhereby pressure or movement of the handle in one direction will openthe valvular elements, and releasing or cessation of the handle pressurewill automatically effect the closure of the valvular elements.

lt further consists of a novel construction of a slidable plunger havinga terminal conical seat, adapted to coact with the closed ported end ofa fixed pipe mounted in a suitable handle or body.

It further consists ofa novel means for concealing and protecting theend of the fixed pipe member aforesaid.

lt further consists of other novel features of construction andadvantage, all as will be hereinafter pointed out in the specificationand claims appended hereto.

It further consists of a novel dispensing nozzle wherein the shut off iseffected at the extreme end of the discharge orice, thus preventing anydrip or wastage of the dispensed fluid after the nozzle has beenclosed.

F or the purpose of illustrating my invention, l have shown in theaccompanying drawing one form thereof which is at present preferred byme, since the same has been found in practice to give satisfactory andreliable results, although it is to be understood that the variousinstrumentalities of whichmy invention consists can be variouslyarranged and organized and that my invention is not Y limited to theprecise arrangement and organization of the instrumentalities as hereiny shown and described.

In carryingout my invention, l employ a tubularcylindrical body orl handle memberlhaving a rear inlet chamber 2, which is threaded at 3 for the attachmentof a suitable hose-4L, which is locked in position with respect to thehandle memberl by the nuts 5 and 6 seen in Figure 1. 'I designates aspring chamber or plunger chamber withmember in openl in the handlemember 1, whichV is .separated i from the rear inlet chamber 2 bythepartil tion 8, said spring chamber having the vent or port 9openingjthereinto from the atmosphere. lOdesignates a fixed inner pipeor stationary tubewhose rearend is tightly fitted 0r fast in thepartition 8 and is secured thereinby the washer 11y and the Iiut v12. 13designaties a slidable plunger which is fitted within the chamber 7,`soas to be readily reciprocated therein,.the rear end of said plunger be-A ing provided with a packing 14 and a packing retainer'15-contiguous tothe spring 16, one` end of which latter bears against said packingretainer 15 while its other end bears*againsty the contiguous wall ofthepartition 8 as willbe understood from Figure 2. The fired in-l ner pipeor tube lOihasits frontend closed` as indicated at 17 and is providedwith the outwardly flared terminal ,conical wall 18 having a port 19therein, said flared terminal wall 18 being seated in the conical lseat20 in the, front end 23 of the nozzle by reason ofthe ten-v sion of thespring 16 when the parts are in the position ,se-en in Figure 2. 21designates aA flange extendingtransversely to the slidable i plunger 13and preferably integral therewith and normally. positionedv with respectto the end 22 of the handle member 1, substantially as seen in Figure2'when the`port'19 is closed, the spring ,'16 serving automatically `to.hold the jslidableplung'fe'r 13 with respect to theI fiXed inner pipe10 normally substantially as seen in Figure 2. When it is desired toconvey fluid to the desired point as to a transmission, it is onlynecessary to insert the forward end 23 of the nozzle into vthe openingof said tra-nsmission until the flange 21 contacts with the Wall of saidtransmission and to push the handle member 1 forwardly whereupon theparts will assume the position seen in Figure 3, the port 19 being openand fluid under pressure being discharged from the hose 4 through thefixed pipe 10 and port 19 to the desired point. Upon removing the fiange21 from the wall of the transmission or releasing slightly the grip orgrasp upon the handle 1, the parts move from the position seen in Figure3 to the position seen in Figure 2 by reason of the tension of thespring 16 the contact of the walls 18 and 2O limiting the eX- tent offorward movement ofthe plunger 13 as is evident. In the constructionseen in Figure 4, I have shown a slightly modified form of device forprotecting the end of the fixed pipe wherein the fixed pipe is indicatedas 24 and is provided with the flared end 25 closed by the relativelythick wall 26 and provided with a port 27. The flared -end 25 isnormally seated against the conical wall 23 of the plunger 33 as seen inFigure 4 and the closed end 26 reciprocates and is protected in thechamber 29 which is provided with the main exit port 30 and the ventport 31. The vent port 31 is preferably positioned in a cap member 32,which is in threaded engagement with the front end of the plunger member33, which is provided with a flange 21 of the same character andfunction as seen in Figures 1 to 3. A

It will be understood that the right hand portion of Figure 4 isconstructed similar to the right hand portion of Figure 2, in respect ofthe threaded portion 3, the partition 8, vent 9, packing 14, and nut 12,so 'that when the flange 21 seen in Figure 4 is pressed against the wallof the chamber into which it is desired to introducev fiuid,the port 27will align with the port 30 and fluid can flow from the hose 4 throughthe fixed pipe 24 and ports 2'2"V and 30 to the desired point. The vent9 permitsthe escape of air when the spring 16 is compressed, and thevent 31 similarly functions when the plunger 33 is actuated with respectto the fixed pipe 24.

I am aware that the invention maybe embodied in other specific formswithout departing from the spirit or essential attributes thereof, and Itherefore desire the present embodiment to be considered in all respectsas illustrative and not restrictive, reference being had to the appendedclaims rather than to the foregoing description to indicate the scope ofthe invention. n

Having thus describedmy inventiomwhat ters Patent, is

I claim as new and desireI to secure by Let-l l. In a device of thecharacter stated, a handle member, having a rear inlet chamber adaptedfor a hose attachment, a front plunger chamber, a partition separatingsaid chambers, a pipe fixed in said partition, open at its rear end andclosed at its front end and provided with an outwardly flaring, conical,terminal portion having a port therein, a plunger carried by said handleand slidable longitudinally upon said fixed pipe, and having a frontterminal conical seat conforming to the lr front contour of said iXedpipe, a flange on the front of said plunger, and a spring intermediatesaid partition and the rear of said plunger.

V2. In a device of the character stated, a handle member, having a rearinlet chamber adapted for a hose attachment, a front plunger chamber, apartition separating said chambers, a pipe fixed in said partition, openat its rear end and closed at its front end and providedwith anoutwardly flaring, conical, terminal portion having a port therein, aplunger carried by said handlev and slidable longitudinally upon saidfixed pipe, and having 'a front terminal conical seat conforming to thefront contour of said fixed pipe, a flange on the front of said plunger,a spring intermediate said partition and the rear of said plunger, andan apertured cap for said plunger covering and protecting the end ofsaid fixed pipe. y
